  • Device for processing water having high concentrations of scale forming compounds and high solids content in a high efficiency vapor compression distillation system
    Patent number: 5810976
    Abstract: A device for processing water having high concentrations of scale forming compounds and high solids content in a high efficiency vapor compression distillation system wherein a plate-in-frame heat exchanger is submerged in a boiling solution contained in a boiler drum. An impeller in the drum continuously circulates the boiling solution through the heat exchanger at a velocity to prevent suspended solids from accumulating and to inhibit scale formation on the boiling surfaces of the heat exchanger.
